Answer: The base pair rule for RNA is that adenine pairs with uracil, thymine pairs with adenine and cytosine pairs with guanine.
Explanation: RNA contains adenine, uracil, cytosine and guanine while DNA contains adenine, thymine, cytosine and guanine. Thymine is not found in RNA while uracil is not found in DNA. In RNA base pairing, Watson and Crick proposed a rule that wherever adenine is found in DNA, Uracil occurs in the complementary RNA strand, wherever thymine is found in the DNA strand, adenine is found in the complementary RNA strand and wherever guanine occurs in the DNA strand, cytosine is found in the complementary RNA strand.
Answer: Cells have different shapes because they do different things. Each cell type has its own role to play in helping our bodies to work properly. Their shapes help them carry out these roles effectively.

In terms of biodiversity, islands are special locations that contain a range of creatures and ecosystems for both native and endangered biodiversity. Endemism is typical of many islands. Thus islands are regarded as hot spots for biodiversity from a regional biodiversity viewpoint. In a collective portion of a basic land ecosystem it is much simpler to conserve species diversity than by shielding only one region of an archipelago.
Since every island has a specific variety of plants and animals, it is important that conservationists preserve the entire island chain. Thus allow the sources of food to differ from island to island in an archipelago. The type of producer originated in an island and then the type of consumers consuming it differ from island to island due to huge variety of and different adaptations of organisms.
Answer:
1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion
3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.
